SAS-callable SUDAAN with SAS University Edition?

[dcnorris]

Is it possible to install SUDAAN for use with SAS University Edition, via 'SAS-callable SUDAAN'?

[ballardw]

I have a sneaking suspicion the response will be "no", if for no other reason that the virtual machine parts.

What are you using SUDAAN for that the SAS survey procs won't cover?

[dcnorris]

@ballardw, Thank you for your reply. My hope would be that perhaps the SUDAAN executable could be installed in another 'shared folder' (like the standard 'myfolder'), and accessed by SAS University Edition much as the executable would be accessed by the usual install of SAS. (The work is a reproduction/reanalysis of published research that used 'PROC RLOGIST', which is 'SAS-callable SUDAAN'.)

[ballardw · Accepted solution]

If you can't get SAS callable to work, you may need to look at exporting data from SAS to text files and using the "native" SUDAAN data structures. A headache but shouldn't be deal breaker.

I haven't had an opportunity to work on the same data with Proc Surveylogistic and Rlogistic but I have worked with Surveyfreq and Surveymeans and get results that matched SUDAAN output to 3 and often more decimals on prevalence estimates. For example a Surveyfreq result might be 43.1234 and SUDAAN would be 43.1235.

Is there a 'sasv9.cfg' file in SAS University Edition? If so, my hope would be to put the SUDAAN SAS-callable code into a subdirectory of the shared 'myfolders', and modify the PATH specification in the sasv9.cfg file along the lines suggested in the SUDAAN Installation Guide:

-PATH (
   !SASROOT/sasexe
   /folders/myfolders/sas-callable
   )

Or is this file not present (or inaccessible) in SAS University Edition? If that's the case, is there an alternative way to change this PATH configuration, e.g. with a SAS command at runtime?

(BTW, @ballardw thanks for the tip on PROC SURVEYLOGISTIC. I'll be sure to give it a try if I'm forced to go the SUDAAN command-line route.)

I can confirm that I got 4th-decimal-place agreement with PROC SURVEYLOGISTIC in a simple application (1 stratum). Standard errors agreed to within ~1% proportionally. Thx! -dcnorris
